<P CLASS=para>
This class represents a dialog box window.  A <tt CLASS=literal>Dialog</tt>
may be modal so that it blocks user input to all other
windows until dismissed, may optionally have a title, and
may be resizable.  A <tt CLASS=literal>Dialog</tt> object is a
<tt CLASS=literal>Container</tt> and <tt CLASS=literal>Component</tt> objects can be added
to it in the normal way with the <tt CLASS=literal>add()</tt> method.  The
default <tt CLASS=literal>LayoutManager</tt> for <tt CLASS=literal>Dialog</tt> is
<tt CLASS=literal>BorderLayout</tt>.  You may specify a different
<tt CLASS=literal>LayoutManager</tt> object with <tt CLASS=literal>setLayout()</tt>.
Call the <tt CLASS=literal>pack()</tt> method of <tt CLASS=literal>Window</tt> to initiate
layout management of the dialog and set its initial size
appropriately. 
Call <tt CLASS=literal>show()</tt> to pop a dialog up, and <tt CLASS=literal>hide()</tt>
to pop it down.  For modal dialogs, <tt CLASS=literal>show()</tt>
blocks until the dialog is dismissed.  Event handling
continues while <tt CLASS=literal>show()</tt> is blocked, using a new event
dispatcher thread.  In Java 1.0, <tt CLASS=literal>show()</tt> is inherited
from <tt CLASS=literal>Window</tt>.  Call the <tt CLASS=literal>Window.dispose()</tt> method
when the <tt CLASS=literal>Dialog</tt> is no longer needed so that its
window system resources may be reused.
